    22  ## Description
    23  
    24  Lists all the networks the Engine `daemon` knows about. This includes the
    25  networks that span across multiple hosts in a cluster.
    26  
    27  ## Examples
    28  
    29  ### List all networks
    30  
    31  ```console
    32  $ docker network ls
    33  NETWORK ID          NAME                DRIVER          SCOPE
    34  7fca4eb8c647        bridge              bridge          local
    35  9f904ee27bf5        none                null            local
    36  cf03ee007fb4        host                host            local
    37  78b03ee04fc4        multi-host          overlay         swarm
    38  ```
    39  
    40  Use the `--no-trunc` option to display the full network id:
    41  
    42  ```console
    43  $ docker network ls --no-trunc
    44  NETWORK ID                                                         NAME                DRIVER           SCOPE
    45  18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3   none                null             local
    46  c288470c46f6c8949c5f7e5099b5b7947b07eabe8d9a27d79a9cbf111adcbf47   host                host             local
    47  7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185   bridge              bridge           local
    48  95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd   foo                 bridge           local
    49  63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161   dev                 bridge           local
    50  ```
    51  
    52  ### <a name="filter"></a> Filtering (--filter)
    53  
    54  The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
    55  is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
    56  Multiple filter flags are combined as an `OR` filter. For example,
    57  `-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.
    58  
    59  The currently supported filters are:
    60  
    61  * driver
    62  * id (network's id)
    63  * label (`label=<key>` or `label=<key>=<value>`)
    64  * name (network's name)
    65  * scope (`swarm|global|local`)
    66  * type (`custom|builtin`)
    67  
    68  #### Driver
    69  
    70  The `driver` filter matches networks based on their driver.
    71  
    72  The following example matches networks with the `bridge` driver:
    73  
    74  ```console
    75  $ docker network ls --filter driver=bridge
    76  NETWORK ID          NAME                DRIVER            SCOPE
    77  db9db329f835        test1               bridge            local
    78  f6e212da9dfd        test2               bridge            local
    79  ```
    80  
    81  #### ID
    82  
    83  The `id` filter matches on all or part of a network's ID.
    84  
    85  The following filter matches all networks with an ID containing the
    86  `63d1ff1f77b0...` string.
    87  
    88  ```console
    89  $ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
    90  NETWORK ID          NAME                DRIVER           SCOPE
    91  63d1ff1f77b0        dev                 bridge           local
    92  ```
    93  
    94  You can also filter for a substring in an ID as this shows:
    95  
    96  ```console
    97  $ docker network ls --filter id=95e74588f40d
    98  NETWORK ID          NAME                DRIVER          SCOPE
    99  95e74588f40d        foo                 bridge          local
   100  
   101  $ docker network ls --filter id=95e
   102  NETWORK ID          NAME                DRIVER          SCOPE
   103  95e74588f40d        foo                 bridge          local
   104  ```
   105  
   106  #### Label
   107  
   108  The `label` filter matches networks based on the presence of a `label` alone or a `label` and a
   109  value.
   110  
   111  The following filter matches networks with the `usage` label regardless of its value.
   112  
   113  ```console
   114  $ docker network ls -f "label=usage"
   115  NETWORK ID          NAME                DRIVER         SCOPE
   116  db9db329f835        test1               bridge         local
   117  f6e212da9dfd        test2               bridge         local
   118  ```
   119  
   120  The following filter matches networks with the `usage` label with the `prod` value.
   121  
   122  ```console
   123  $ docker network ls -f "label=usage=prod"
   124  NETWORK ID          NAME                DRIVER        SCOPE
   125  f6e212da9dfd        test2               bridge        local
   126  ```
   127  
   128  #### Name
   129  
   130  The `name` filter matches on all or part of a network's name.
   131  
   132  The following filter matches all networks with a name containing the `foobar` string.
   133  
   134  ```console
   135  $ docker network ls --filter name=foobar
   136  NETWORK ID          NAME                DRIVER       SCOPE
   137  06e7eef0a170        foobar              bridge       local
   138  ```
   139  
   140  You can also filter for a substring in a name as this shows:
   141  
   142  ```console
   143  $ docker network ls --filter name=foo
   144  NETWORK ID          NAME                DRIVER       SCOPE
   145  95e74588f40d        foo                 bridge       local
   146  06e7eef0a170        foobar              bridge       local
   147  ```
   148  
   149  #### Scope
   150  
   151  The `scope` filter matches networks based on their scope.
   152  
   153  The following example matches networks with the `swarm` scope:
   154  
   155  ```console
   156  $ docker network ls --filter scope=swarm
   157  NETWORK ID          NAME                DRIVER              SCOPE
   158  xbtm0v4f1lfh        ingress             overlay             swarm
   159  ic6r88twuu92        swarmnet            overlay             swarm
   160  ```
   161  
   162  The following example matches networks with the `local` scope:
   163  
   164  ```console
   165  $ docker network ls --filter scope=local
   166  NETWORK ID          NAME                DRIVER              SCOPE
   167  e85227439ac7        bridge              bridge              local
   168  0ca0e19443ed        host                host                local
   169  ca13cc149a36        localnet            bridge              local
   170  f9e115d2de35        none                null                local
   171  ```
   172  
   173  #### Type
   174  
   175  The `type` filter supports two values; `builtin` displays predefined networks
   176  (`bridge`, `none`, `host`), whereas `custom` displays user defined networks.
   177  
   178  The following filter matches all user defined networks:
   179  
   180  ```console
   181  $ docker network ls --filter type=custom
   182  NETWORK ID          NAME                DRIVER       SCOPE
   183  95e74588f40d        foo                 bridge       local
   184  63d1ff1f77b0        dev                 bridge       local
   185  ```
   186  
   187  By having this flag it allows for batch cleanup. For example, use this filter
   188  to delete all user defined networks:
   189  
   190  ```console
   191  $ docker network rm `docker network ls --filter type=custom -q`
   192  ```
   193  
   194  A warning will be issued when trying to remove a network that has containers
   195  attached.
   196  
   197  ### <a name="format"></a> Format the output (--format)
   198  
   199  The formatting options (`--format`) pretty-prints networks output
   200  using a Go template.
   201  
   202  Valid placeholders for the Go template are listed below:
   203  
   204  | Placeholder  | Description                                                                            |
   205  |--------------|----------------------------------------------------------------------------------------|
   206  | `.ID`        | Network ID                                                                             |
   207  | `.Name`      | Network name                                                                           |
   208  | `.Driver`    | Network driver                                                                         |
   209  | `.Scope`     | Network scope (local, global)                                                          |
   210  | `.IPv6`      | Whether IPv6 is enabled on the network or not.                                         |
   211  | `.Internal`  | Whether the network is internal or not.                                                |
   212  | `.Labels`    | All labels assigned to the network.                                                    |
   213  | `.Label`     | Value of a specific label for this network. For example `{{.Label "project.version"}}` |
   214  | `.CreatedAt` | Time when the network was created                                                      |
   215  
   216  When using the `--format` option, the `network ls` command will either
   217  output the data exactly as the template declares or, when using the
   218  `table` directive, includes column headers as well.
   219  
   220  The following example uses a template without headers and outputs the
   221  `ID` and `Driver` entries separated by a colon (`:`) for all networks:
   222  
   223  ```console
   224  $ docker network ls --format "{{.ID}}: {{.Driver}}"
   225  afaaab448eb2: bridge
   226  d1584f8dc718: host
   227  391df270dc66: null
   228  ```
   229  
   230  To list all networks in JSON format, use the `json` directive:
   231  
   232  ```console
   233  $ docker network ls --format json
   234  {"CreatedAt":"2021-03-09 21:41:29.798999529 +0000 UTC","Driver":"bridge","ID":"f33ba176dd8e","IPv6":"false","Internal":"false","Labels":"","Name":"bridge","Scope":"local"}
